For scenario and special event use (which is the main reason to add an L'24 right now), we can disable certian loadouts and weapons. It would work much better than the Panzer IV H we have now, and about as well as an Ausf. D.
And if I'm the type to fly 109E's, M8s, M4(75)'s, Ki-61's, and other less-than-stellar rides, why wouldn't I take the L'24? Would be funny as hell to take out someone's Panther tank with a low velocity 75mm round from the side.
